Skinners are especially good for guys like me who wear progressive lenses. Putting a good peep sight on a rifle eliminates the need to line up both a front and rear iron sight which is difficult with this type of lens. Instead, you instinctively look through the hole in the rear sight and only focus on your front sight, which of course is where your focus should be directed anyway. Target acquisition is much faster and hitting the bullseye is more consistent with less room for error.
Below are some of the rifles I've owned over the past ten years with their mounted Skinners. In the past I've posted so many photos of my small game hunts with Skinners on my Henry's that Henry Repeating Arms finally came out with their own small game carbine (see last photo) with Skinners as standard equipment. I think they should have named the rifle after me!
